and against good opps it just paves the way for their declarer play better to wait and balance if necessary
Not really. It's the good opps that are driving necessity of this with their light openings and responses. If you wait, balancing action is still often unclear, you defend some partial of theirs undoubled down 2 and meanwhile you could have rang up 3nt if partner knew what you had. Risk of good opps stealing you blind is > risk of them axing you or playing more accurately.

If you've got Roth-stone opener and responder with always 6+, then definitely there is less upside in this treatment. But these days opening can be 10 and response can be 2, I've definitely seen it happen! Even if you don't have game, sometimes this helps your side grab its partial when partner wasn't strong enough to overcall their long suit, and that can be enough.
