I respectfully must slightly disagree with you.
In terms of security fixes and new hardware drivers, the issues of
backporting (that is, to make a bit of software compatible -- buildable
-- with the core gcc/g++ environment of a "very old" Linux, including
SL) may require a great deal of work. Unlike those environments that
use "micro-kernels", Linux (thanks to Torvalds' insistence) is a
monolith, and changing one aspect of a monolith often changes many other
aspects. (A micro-kernel -- "Mach" -- approach more easily can have
encapsulation and "isolation.)
New hardware drivers are needed if one is using the environment on a
platform that has "current" hardware for which new hardware drivers are
needed. This is more common on a laptop workstation, but happens on
servers and real-time control and data acquisition systems (e.g., the
experimental environment of HEP).
Could an SL7 base be kept up to date on these issues? Probably.
However, a technical staff of a few (less than five) full time
professionals might not suffice given the number of lines of source code
that are involved. Moreover, the current professionals who maintained
SL at Fermilab/CERN may not want to be involved, given that each may
have a "permanent" "real job" position at Fermilab/CERN or a
participating entity (e.g. a university). Thus, your subscription model
may not be practical -- and the use of volunteers or compensated "Gig
economy" "workers" does not result in stability. Stability requires
compensated permanent professionals (except for those who are
independently "wealthy" and are willing to be permanent "volunteers", an
unlike staff arrangement).

How much work (staff hours per year, plus volunteer help)
would it take to do JUST (1) and (2) for Scientific Linux
7.8, 7.9,... forever, assuming that RHEL and Debian
sources were available for plagiarism?
I (and perhaps others) chose SL because it was stable.
I do not need to rebuild my working environment to adapt
to changing fashion. I get SL for free now (thank you!)
but I wouldn't mind paying an annual subscription fee to
support a small team "keeping the plumbing water-tight
and sanitary". WITHOUT hiding the sink and changing
the knobs, which is what I would get from RedHat/IBM.
How many of us are willing to pay for this, and to
create, contribute, and maintain scientific "extras"
(like the source code for the data reduction for my
published papers) to share with our small community?
