Agreed, there should be a way to read and write them.  But that's
been required in every standard, for a long time.

My question was a step back from that; it was whether it is
necessary to specify a particular syntax for them to be
read and written in.

If so, let there be ONE such syntax in the standard.  If
an implementation provides others, that's not a conformance
issue.

If not, all we need to say is that implementations must
implement read/write invariance on all symbols, including
those resulting from string->symbol.
