The semi-colon is semi-deprecated, nevertheless it is the standard method
of indicating that a tag has multiple
values even if a particular tag does not explicitly say it can be used.

I wouldn't worry about validators flagging it as an error.  By the nature
of things they always lag behind new
tagging.  JOSM flagging it as an error is only a serious problem if it
refuses to let you save it.

As for data consumers, maybe this would work (I haven't thought through all
the ramifications).  Create a route
with route=hiking;bicycle.  Then create two route masters, one with
route_master=hiking and the other with
route_master=bicycle; each route master includes the common
route=hiking;bicycle.  This might solve some
problems.  It will also likely cause different problems.

The alternative, of course, is to use JOSM to clone the route, set one copy
to route=hiking and the other copy to
route=bicycle.  But that will be a pain in the bum to maintain the route
