You are describing a transitioning over to DRM - which is Ok.
But on that way there is no need to ignore, deny or even kill usage scenarios
which are different compared to your usage scenarios (e.g. embedded devices,
old platforms, slow devices, slow busses, no 3D hardware features,
low-color devices, ...).

All of those should be handled by the drm layer, as Daniel keeps
pointing out.  If not, then the tinydrm layer needs to be enhanced to do
so.

Anyone have a pointer to hardware I can buy that is one of these fbtft
drivers that I could do a port to drm to see just how much work is
really needed here?

I have bought myself (for other purposes, I mean not to convert the driver(s))
SSD1306 based display (SPI), SSD1331 (SPI), HX88347d (parallel).

Each of them costed less than $10 with delivery to EU (nowadays maybe a bit
more expensive). I believe it's very easy to find the links on AliExpress.
