Do note, though, the removed verbiage only applies to source builds. Other means of running Python (nuget, winget, installer) work as is. I would say workflows that clone a released Python branch and build it to run pyperformance would be better served using the released binary for the comparison.

For example:

nuget.exe install python -Version 3.10 [-OutputDirectory <dir>]

will download and unpack the released distribution for 3.10.0 to <dir>\python as a full usable interpreter (<dir>\python\tools\python.exe). This already is done in the build scripts just to build the interpreter now[1].
nuget.exe is also available in the <srcdir>\externals directory (see [1]). This has the added benefit of guaranteeing isolation from previous builds.

[1] Unless there is an existing Python installation usable for building.
