I upgraded a PC from 1.1 to -current about a week or so ago.  (March 1st sup)
I'll add my US $0.02, in case it helps anyone contemplating same.

These must be recent; I didn't have to do this.

I don't remember having to do this either ...

Vitally important, or else the "make build" will puke on the .../man9 stuff.

I took a slightly different tack.  I bit the bullet and did the new gcc
installation first.  That caused everything that got compiled with the newly
installed gcc to complain about libc.so.12.3 being older than the now-expected
libc.so.12.4, so I went to libc and "make ; make install" in there to fix
that.

Once I did that, the build was pretty smooth, but it fell over down in the
/usr/src/domestic stuff.  A lot of things were *really* unhappy (compile-wise)
because they all expected the new (i.e. -current instead of 1.1) libtelnet.so
to be installed (from the domestic area, not the mainline/international one).

I think there may have been one other step needed to make an entire
"make build" cruise through without errors but it's late ...
