FAA to be phasing out "position and hold" in the US

What's implicit about it?

everything.

If you're cleared to taxi to runway XX and
runways YY and ZZ are between you and runway XX then are you not explicitly
cleared to cross runways YY and ZZ?

No.

How else could you comply with the
clearance to taxi to runway XX?

That is the essence of an implicit clearance. "How else could you do it?"
