How often do you need to consult a command about foo-mode while working
on a buffer with baz-mode ?

Why using M-x is more convenient for you than using C-h a, C-h f or some
other facility?
I'm trying to understand the mindset of those like you that use M-x for
exploring features or remembering commands. I use M-x for both purposes
all the time, but almost always I want to do something with that
command, which implies that I'm working on a context where the command
that I'm interested on will pass the filter. Thus, the filtering is a
great improvement.

Almost all commands fall into two categories: specific to some mode
(which means that they only work if the mode is active) or general. I
see no problem classifying the commands that way.
I'm skeptic about other uses for the filtering that were mentioned, such
as adding predicates that test if a region is active, etc. That looks as
anti-feature to me. There are times when a menu entry should be hidden
and times where it should be grayed out (inactive). Likewise, a command
should not be hidden when it is related to the current context but a
detail makes it inapplicable. Just allow it to be invoked and throw an
user-error informing the user about what's wrong.
