`erc-before-connect' and `erc-after-connect' are abnormal hooks,
so I think they should each have the suffix "-functions" for
consistency, and so that they are easier to discover.
Is is ok to rename them and defvaralias the old names?
All other erc hooks have the -hook or -functions suffix, so far
as I can see.
For reference:
(defcustom erc-before-connect nil
"Hook called before connecting to a server.
This hook gets executed before `erc' actually invokes `erc-mode'
with your input data. The functions in here get called with three
parameters, SERVER, PORT and NICK."
:group 'erc-hooks
:type 'hook)
(defcustom erc-after-connect nil
"Hook called after connecting to a server.
This hook gets executed when an end of MOTD has been received. All
functions in here get called with the parameters SERVER and NICK."
:group 'erc-hooks
:type 'hook)

I've pushed branch fix/bug-34657-erc-hooks for this, and I've used
define-obsolete-variable-alias, but there are problems with the
customize behaviour.
The first annoyance is that in customize-group erc-hooks the alias
is displayed (albeit slightly differently) as well as the renamed
option. I feel that it would be cleaner if the alias did not appear
in the customize UI, as otherwise it can lead to a weird state where
the user edits both of them in the customize UI with different
values, and one value clobbers the other.
The latter aspect is really a more general problem, though, which
we can arrive at more simply:
1. The user has previously customized `erc-before-connect'
(for example) such that their custom file contains a value.
2. They NOW customize the option under its new name, and this
`erc-before-connect-functions' value is saved *separately* to
the custom file.
3. We are now in the same situation as before -- *both* option
names exist in the custom file, potentially with different
values.
4. When starting Emacs, the first(?) value processed is the
one which sticks for both names, which can mean that the user's
customization of the new name didn't work in practice.
I can think of a possible reason for not deleting the old option
from the custom file (being that the user *potentially* uses their
config with Emacs 27 and Emacs 26, and 26 would only use the old
name). I'm not sure whether switching back and forth like that is
a supported case, though?
Regardless of that, allowing both options to be written with
*different* values seems like a definite bug?

Isn't there some precedent for handling this?
If we never did rename a defcustom before, and no simple solution
presents itself, I'd rather drop the idea altogether. ERC is a niche
package, so it's not a catastrophe if we have exceptions from the rule
here.
Thanks.
(What is the second annoyance?)

Hopefully. If not, I guess I'll raise a separate bug for the fact
that renaming defcustoms is problematic, and maybe just add a code
comment referencing that to erc.el.
> (What is the second annoyance?)
A proof-reading failure :) I'd initially worded things differently,
before deciding that the issues I was seeing were all connected, so
I did cover all the problems I'd observed.

This was over a year ago, and nobody piped up, so I'm guessing that
there isn't a way for defcustom to deal with renamed variables?
In which case I agree with Eli -- it just isn't worth doing the
renaming.

Shouldn't we just fix defcustom?

From :type 'hook to 'function or something? Yup.
