[arch-general] AUR - Best Practices when Package no longer Supported for Linux upstream but LTS fine?

Arch devs, Quick AUR question. The virtualbox 5.2 branch is unsupported as of July 2020. Oracle continues to put out testbuilds for 5.2, but currently it does not build with 5.8 (LTS is fine). I am still awaiting answers on the vbox-end-users list as to whether anything compatible will be released either as a testbuild case or as a release (Oracle seems a bit undecided) If 5.2.44 was the last release and there will be no update to support Linux 5.8 -- what do I do with the package? Do I mark it LTS only in some way, or just have it removed? -- David C. Rankin, J.D.,P.E.
