At least for PI space, they explicitly say they don't.  (Of course, this
doesn't completely rule out that an implied guarantee exists
nevertheless.)

Yes, it's a mandatory part of the contract, the leaser cannot abstain
from that.  You've got some wiggle room with regard to the scope of the
contract.  But a lease of something that provides no documented value
(and the contract explicitly saying so!) will be a very difficult sell
to various parties.  It borders on breach of trust ("Untreue",
embezzlement in extreme cases).  The current model of industry
self-governance does not seem to suffer from that.
