That's the publicly-visible servers, i.e. standard PCs (including ones in
racks in data centres).  In the embedded space, support for TLS 1.2 is... low.
OS-based support (e.g. in VxWorks, claimed to be the world most widely-used
RTOS) is nonexistent, you need to go to third-party libraries for this, and
even then it's not common.

For embedded it's going to be much longer than that...
