Not really. Building Emacs is much harder than installing gdb, execute
emacs under gdb and obtain an stack trace.

Debug symbols are useful, and that is the reason why GNU/Linux
distributions offer them as a separate package.

As explained on a previous post, IMO the reasoning behind that practice
makes little sense for Windows.

Creating symlinks on Windows (pre-10, IIRC) require administrator
privileges. Ditto for enabling NTFS compression.

About what is small and what isn't: that's a personal opinion. I'm mildly
annoyed about the fact that yesterday's MB are today's GB, without a
proportional increase in functionality. Also, I recently started using
an Android tablet with 32 GB storage and I really appreciate how the
Termux guys manage to produce packages that are significantly smaller
than those on desktop GNU/Linux. There are low-end computers in stores
with 32 GB SSDs. And people use old hardware too.

-O3 does not necessarily mean better performance. My bet is that the
difference will be insignificant for Emacs. I've seen plenty of cases
where -O3 was measurably worse than -O2.
