I think thats the right move re 1.0.2 support. 1.0.2 is also the version in
RHEL7 which is in ELS until 2026.

When we moved the goalposts to 1.0.1 (commit 7b283d0e1d1) we referred to RHEL6
using 1.0.1, and RHEL6 goes out of ELS in late June 2024 seems possible to drop
1.0.1 support during v17. I haven't studied the patch yet but I'll have a look
at it.

It would be nice it the OpenSSL project could grant us an LTS license for a
buildfarm animal to ensure compatibility but I have no idea how realistic that
is (or how much the LTS version of 1.0.2 has diverged from the last available
public 1.0.2 version).
