I think it depends on the tokenomics of the specific project. If you are minting an unlimited supply of a coin, then having burning mechanisms in place make sense to keep down the supply in the long run. If you are doing a limited amount of tokens, then burning makes a lot less sense to me.

It also really depends what the use case is for the said token. Unfortunately, the use case is often simply to try make a token just for the sake of making one (or, making a profit) and burning is used to try to pump the perceived value.
