Ouch!

"It works just fine here."  Please define "works",
and "here".

If I understand this right then yes, I object strongly.
(It's possible I don't understand it right, however.)

1. What goes in an autoload should have nothing to do
with whether `lexical-binding' gets turned on for a
file to be autoloaded.  No?

2. The code you've changed, IIUC, is used in multiple
places, including user functions such as
`update-directory-autoloads' and
`autoload-generate-file-autoloads'.

Why on earth would we assume that a user who wants to
update her autoloads for a given user directory or
file would necessarily want to force the code to use
`lexical-binding'=t?

Please back off with the eagerness to paint
`lexical-binding' everywhere.  Things like this should
be handled case by case, carefully.  Spray-painting
this way is not TRT, IMO.  Sprinkling can, not fire
hose, please.  We'll get to the CL approach to lexical
& dynamic binding eventually, petit a petit.
