In addition to Urborg and Hammerheim, Ishkanah, Grafwidow, Kenrith, the Returned King, and Doran, the Siege Tower are legendary cards that receive similar treatment
If your lands are never going to untap, there's little harm in sacrificing them and turning each land into two mana makes the upkeep on Stasis maintainable on a permanent basis
However, if youre neck and neck this could be a problem, giving your opponent the resources they need to come back and win
Of course, this is only as good as the spell you get back, and a flashback card that you get back from exile is like drawing two whole cards for the price of one
