Things goes out of support all the time.

CPU architectures (ISA).

OS. Either completely or on specific CPU architecture.

Database servers, web servers, application servers,
message queue servers, cache servers etc.. Either completely
or on specific OS or on specific OS and CPU architecture
combination.

Libraries.

Shrinking OS are obviously harder hit than growing OS, but
it is far from a VMS specific problem.

Of course it is a problem.

Remember what happened when Oracle announced that they would
drop support for VMS in Oracle DB client library? Not only was it a
problem for those using Oracle DB, but it also worried those
using Oracle Rdb a bit.

Bottom line: lots of hope but nothing sure.

Most businesses will prefer a technology where they know
they can get people over a technology where they hope
they can get people.

Not true.

It will get you on a supported platform where you can
easily  get people with the skills.

Yes - a migration come with some risk.

Main risk mitigation factor is the skills of those
doing the migration.
