I should hope implementations like that are dying off, especially since
the SVID says that VMIN and VTIME should work the way they're documented
in the "termio" man page....

You mean "vendor dependent".  As distributed by AT&T, VMIN and VTIME are
handled by the line discipline, not by the serial port driver, so it
should, at least in principle, work the same for all terminal muxes.  I
think the intent is to do so in the S5R4 streams-based tty mechanism as
well, so that it'll be handled by a streams module, not the driver (the
SunOS 4.0 streams-based driver does it in a streams module and the
stream head).
