This sounds like a good idea to me. Thumbs up.

I specifically do not suggest that we should define any kind of default for

Agree with that, though one could argue that maybe there should be an
"available default", e.g.

    --standard-compress-exts    Apply a standard set of no-compression
extensions.
                                Equivalent to:
--no-compress-ext=.jpg:.png:.gz

But that would introduce a new debate about what that list should be, and
how it should evolve over time (possibly introducing variability into
people's builds). So again probably best to completely avoid any "opinions"
and leave all decisions up to the user.
