Different glyph formats, obviously, but also different OTL features and different hinting. Perhaps more, but seeing that, that's a sufficient set of differentiation to conclude they're not interchangeable. Folks can verify that with a basic: ttx -l FONTNAME.ttf ttx -l FONTNAME.otf and go into more detail on a per-table basis as desired, also with ttx. So they differ considerably in how they behave, and there may well be target systems or downstream packages that reply on one where the other would not do. If the byte size is a concern for someone, they could perhaps make a case instead that there should be separate packages for the build variants/flavors (e.g., fonts-libertinus-tt and fonts-libertinus-cff) with a metapackage that provides access to both, but that's probably a maintainer's decision given all that would be involved.
