Not necessarily. Some distros are better for easy customizing than
others, but in the end you can always run your own package repos
(which, in fact, I'm doing regularily).

OTOH, the question often is, whether customizing is really worth the
effort for a particular use case.

Correct, much of today's software as grown insanely huge and complex.
Browsers (and GUI stuff in general) are probably the best example of
ugly bloat code and bad engineering (beginning w/ lack of modularity).

IMHO, we should work closer w/ upstreams and other distros to improve
the packages step by step. Sometime this also requires some radical
steps.

Correct. But look at the commercial projects Mozilla: they're
trying to roll their operating system, completely ignoring basic
concepts like modularity and package management, and are pretty
learning resistant. At some point you'll have to decide whether
it's worth to invest any resources at all or just drop the whole
code completely.

At that point we could go that route consequently and introduce a
strict separation between an init-OS and an main-OS, maybe even move
to some container environment. That idea needs some deeper thoughts ...

Probably. But it takes a lot of time for systems maintenance.
Aeons ago, I've been maintainer of an LFS derivative (l4g) - that was
a really good learning experience, but I wouldn't use it for production.

For some use cases, I'd rather think of building customized images via
PTXDist, maybe run them in chroots or containers.

Can't tell anymore, it's sooo long ago. But I've spent really huge
amount of time. Maybe it's much easier now, or maybe it's much more
complex as today's software had become so complex. No idea.

What are the actual use cases you have in mind ?
