Should *occur* have an undo?

[Richard.G.Bielawski]

Sometimes when using occur on a really big file and looking for something that occurs many times it stops with a prompt like

 

Buffer *Occur* undo info is 3012400 bytes long; discard it? (yes or no)

 

Is there really any usefulness to undo being turned on in an occur buffer?

There are probably overhead benefits to turning it off. 

Not to mention getting rid of this annoying prompt. 

Which, by the way, screws up keyboard macros that invoke occur.
