Why do you think that if we use larger modules these things would get
harder?

There's already applications on the CPAN which can do "fat
packing". I.e. you could use Plack, Catalyst, Template and whatever
else but run some make target to pack gitweb and all its dependencies
into a single file.

Obviously it would be really big, and probably slow unless you ran it
as a fastcgi script. But that would be a tradeoff for making the
source easier to maintain.

But packing things like these is not a technical challange at all, and
probably way easier than reinventing the wheel each time you need some
small thing that's not in core, but is in a popular & well tested CPAN
module.
