Does normalize_version work here? It’d be much cheaper than constructing a Version object and converting it immediately back to str.

Sorry for the late reply, I was away on vacation with limited time to answer and bad internet access.

canonicalize_version works with strip_trailing_zero=False. However, I doubt it'll be cheaper given it does the same thing: construct a Version object and builds a string similar to Version.__str__ with added conditional statements on strip_trailing_zero and version argument type check.
I can understand that it's clearer with canonicalize_version and can go this way if clarity beats speed cost here.

Clarity (almost) always beats speed. 🙂

In case of prefix version matching, normalization of the version was not applied to the specifier's version. This resulted in `2` being rejected as a candidate for `==0!2.*` With normalization applied, the candidate is now accepted.
