[question] boost: building multiple boost_python versions?

[markferry]

Boost (>=1.67) supports building multiple versions of boost_pythonXX for various python versions.

How could this support be added to the conan-center boost recipe?

I've attempted to parameterize the recipe in this (draft) PR: #11998

It build the libs but there are issues concerning the package ID.

In particular the value of -o boost:python_version='2.7,3.6,3.8' is simply a string.
It will not match, for example, boost:python_version=3.8.

Any cunning ideas on how I can support this?

Split boost_pythonXX out to separate recipes?
