Some related notes from bep:

Just a side-note: I have added some comments in https://github.com/bep/hugo-testing-git-versions/blob/main/hugo.toml re

• With the latest cache improvement commits, I think the strategy used in that project could be useful (I will not delete that project, but I may improveit)
• We currently have a glossary term "glob slice", which isn't covering all of what it does anymore ... In the above comments I use "dimension guery", but I'm not sure.
• I have added == and != to the operators to make it complete.

Example:

[module.imports.mounts.sites.matrix]
    # This is a Hugo dimension query.
    # This can be either a string or a list of strings.
    # If prefixed with an operator, the logical operation is AND and it short-circuits on the first match.
    # If not prefixed with an operator, the logical operation is OR.
    # If not prefixed with an operator or the operator is "! ", it is treated as a Glob expression. See https://github.com/gobwas/glob for the library used.
    # The operators are: !,==, !=, <, <=, >, >= followed by a single space.
    # "! " operator is reserved for Glob expressions.
    # The other operators must be followed by a valid value for the given dimension (for versions Hugo consider semantic equality when finding the value, 
    # so e.g "< v3.0.0" would match v1 and v2).
    versions = 'v1'
