I do not really see harm in having this script that can output the version into different formats is helpful when running external scripts. Also in the future we are most like going to replace the build system and then we would need to add this support to that build system and having it in a standalone script is easier manage in the long run.

"make showversion" is here for several years.
Usually we do not implement the same thing in several places
without a good reason.
And some users can use the old command.
Especially when talking about versions, it is very convenient
to use the same command in every versions.

That's why I insist: why implementing it differently?
If it is only about the new build system, it should be part
of the build system migration plan (long term).
