I dont know about the term implied limping but I would say its more down to table evaluation, if the game is loose passive then limping in with 55 utg and playing no set no bet is a touch loose for my standards but isnt really a mistake.

If the game has been loose agressive or tight passive I would be folding not looking to limp hoping to get other limpers, in those situations if you are planning on playing fives open raising is better than open limping.

More limpers generally encourages more callers but I dont think in agressive games it discourages later raisers.

I dont think its useful as a concept as I would make the borderline decisions based on table texture than this theory.

If you want to play more hands I would go for the theory of adding another table and playing more premium hands than looking for reasons to play marginal hands on your current tables.
