Hi,

some software perhaps could be upgraded easily, but unlikely that there
is any chance to update software that is based on dependencies to a
wholesale framework. The biggest problem are dependencies to shared
libraries, https://en.wikipedia.org/wiki/Soname. It's possible to keep
several versions of a shared library, but not by updating a package,
since this replaces the old files, by new files. So, no, the sensible
way, pinning, doesn't help you with adding new software to a long-term
support release. Even if it would be possible, it wouldn't make sense
to do so, since this would break spirit and purpose of a long-term
support release. However, if you anyway wish to upgrade to software
that depends to a wholesale framework, and you would be willing to
resolve all dependencies, it would become more or less equal to a
release upgrade.

Regards,
Ralf
