Should the latex-bin package depend on luahbtex so lualatex can be correctly installed?

[Yihui Xie]

Hi,

With TeX Live 2020, when I install the latex-bin package, lualatex
cannot be installed because luabhtex is not installed (see the log
below). Is this expected, or should latex-bin depend on luahbtex so
the latter can be automatically installed? Thanks!
