   Need to clean these up as they’ll start causing CI failures as soon as any CI is using 6.10.0 (probably native macos as soon as brew ships the 6.10.0 update).

   Out of curiosity, which distro or package manager ships Qt 6.10?

   Probably any rolling distro? brew will be once https://github.com/Homebrew/homebrew-core/pull/247354 is merged.
