Yeah, there is no way to force specific timings, which makes generating NTSC
modelines on Wayland impossible outside of using switchres to generate custom
EDIDs and applying those. There is also no flag to enable interlacing, which is
an important feature to include for use with CRTs. It would be nice to have
support for full X11-style modelines in Plasma Wayland.
