OTOH, if you use EFI, then you can't use sc(4).  You get no working console
with EFI (which is becoming more popular) if you use sc(4).  You also do
not get non-ASCII characters with sc(4), so you don't have a UTF-8 capable
console if you use sc(4).  You also do not have a working console after
loading the KMS drivers (either by starting X or via explicit kldload) when
using sc(4).  This affects just about every modern Intel system using an
Intel GPU (so more widespread than EFI even).

There are tradeoffs in both directions.  Neither console is a subset of the
other.  However, sc(4) is not really extendable to support the things it is
missing.  vt(4) is actively worked on, and patches for the features it lacks
that you need are certainly welcomed.
