I'm actually replying to this thread using a very alike machine, a
Core 2 Duo T7250 with just ss3, using (almost) latest Plasma and used
as media center, kid's playground, checking email in non office
time...

Keeping the distros able to use whatever baseline is indeed a first
good step, but I'm also thinking about proprietary apps that might be
using tQtC's build for their offerings. We used this very same machine
with Zoom meetings for our kids' school meetings while they couldn't
go to school due to COVID. It proved very useful.

I don't know if the linker capability in using the right library
version can be used in these specific cases, but if somehow it could
be done it would be just wonderful.
