Is there any reason why hodling wETH would be a bad idea?

Sorry if this has been asked before (I did search but could not find anything), or if this is a dumb question.

I was just wondering if it's safe to hold wETH long term. My mining is paid out in wETH on Polygon and if I can avoid the fee to bridge it that would be NAIS!

As far as I've been able to gather, the fact that the smart contract is there and won't change suggests that it's going to be fine for eternity. Is that correct, or are there other factors? Maybe there are possible regulatory concerns in the future?

For clarity, by "long term" I mean several years.
