Question on 24bit color support

[leath-dub]

Upon research neovim uses setrgbf and setrgbb terminfo extensions for termguicolors and termguicursors. Even if I install these locally is it fundamentally unsupported by mtm - I understand and agree if this is a choice for compatibility.

Any info would be very helpful, as in the end I may just fork to support those extensions, thanks in advance :>
