Verified with LO 6.4.3 downloaded form libreoffice.org which should be built with SDK 10.15 and hack. Concerning dark mode behaviour is the same as built with SDK 10.13. Color changes by the OS do not take place. Prior to switching to SDK 10.13 or using hack there were some color changes required for dark mode (see tdf#131286 for an example).

When building LO without hack and SDK 10.15 UI coloring changes after switching to dark mode (e.g. toolbar and sidebar shading, highlight color).  As there is no specific implementation of LO's native colors for dark mode currently, this looks very incomplete. Color changes done by macOS disapper when building with SDK 10.13. For now this is reasonable as of missing specific implementation - better no dark mode than very incomplete dark mode. As I am building with SDK 10.13 for the time being, I can do a retest with SDK 10.15 and hack occasionally - only to be really sure that behaviour of building with SDK 10.13 has no difference from building with SDK 10.15 and hack for this case.

Are you sure that the stripped LC_VERSION_MIN_MACOSX 10.15 load command would negatively impact dark mode if dark mode were actually implemented (at all or correctly---I have no idea about the status there) in LO, or is that speculation on your part?

What are other features besides the "e.g. dark mode" that are negatively affected by the stripped LC_VERSION_MIN_MACOSX 10.15 load command?

My understanding is that that commit does allow to build with SDK 10.15 and at the same time avoid blurry text.  But, as it strips a LC_VERSION_MIN_MACOSX 10.15 load command from the soffice executable, it might negatively affect other macOS 10.15 features, is that what you mean?
