To provide a 0.02$ answer to that question, last night, I went around
and looked for the many amount of tools that can be used to take care
of the continuous integration & continuous delivery, testing (both
performance as well as debugging) and other assorted tools to help
putting out the best releases of software as possible. The list is
included below and include both userspace tools as well as Linux kernel
tools (selftest, memleaks, kasan & ubsan...)

The thing is, some software are famous for API and / or ABI breakage
despite their release cycles (short like 2 weeks to a month, long like
yearly releases). Which software? that is irrelevant.

The few reasons I am working on that at the moment is purely for my own
big@ss selfish benefits in that I was / am working for a long time as a
computer tech, sysadmin, software developer and testing and I became
irritated enough time by quality issues in build-it yourself distros
(gentoo, funtoo, LFS+BLFS...among them, LFS+BLFS is the best quality
one so far) that I want to put up a home server which will do nothing
but testing using the toolset and releasing distributions images
(kernel + userspace selected for various tasks, workstation or server).

Side benefit is that, as soon as breakage happen (say, after a
particular commit or something), I get to know immediately and report;
optionally, provide a patch (which is my intended goal, short to
medium-term).

Look at it this way. It is popular in software company to use scrum
methodology and cut a release (internal or external) every two weeks,
or, on a monthly basis with frequent new features but it can and does
happen that a particular scrum cycle can be used for refactoring / bug
fixes purpose with no new features added (I can't provide any more
details than that).

In many of those companies (those existing since a long time), it took
some massive effort to migrate to a scrum based methodology from a
waterfall methodology. It is my impression (and as always, I could be
wrong), a similar pain look like it happen here.

I won't comment on scrapping a release (number) but I do hope that the
system I'm working on will prove useful when it is done and I can make
it available.

My constraints is that I can't provide any deadline for it given that
my medical care now right now is tying up between 15 and 25 hours per
weeks of work (medical consult, homework, helping with the number of
differential diagnoses and some medical literature review to offload my
medical team) for the next few years.

ultimately, I think frequent releases will prove useful but before,
there is some pain needing to be overcome first.
