> Having to install a heavyweight IDE xcode-select --install pulls in the CLT, which is a fairly reasonably sized download given that it includes various essential dev tools including python3 but without Xcode. This is hinted at by attempting to run python3 before any install, which calls a stub prompting you to do just that. py2/ruby/perl/etc... are part of the base OS for backwards compatibility/expectations (because they were so before Xcode/CLT were even a thing) but have been marked as due for removal from base for something like half a decade. My bet is that at some point they will move to the CLT (or some other optional download) as well.
