But if you look in the systemd repo there is a TODO file with a section of libraries which needs to be lazy loaded.
liblzma was added in this list in June 2020 (https://github.com/systemd/systemd/commit/cdfd853744ee934869...) by Lennart, and removed by me just after that my PR was merged.
To be more precise, the first public comment asking to dlopenify lzma was dated 30 Jan by Daan: https://github.com/systemd/systemd/pull/31131#issuecomment-1...
The day after, it was reiterated by Lennart: https://github.com/systemd/systemd/pull/31131#issuecomment-1...
