I think it does tell what people need to know; see DJ's message which
actually enumerates all the registers.

Those who write assembly code surely need to know that.

I think both of these should be preserved.  It is true that FS is not

either in third-party libraries or in inline assembly in the
application code, could use it.  Better be safe than sorry.
