Best practice on Local/Mage module

Question

I have a developer who is saying we don't need to bother to convert a local/Mage module that does not override core to a local/Module namespace. I was under the assumption we should never user local/Mage and we have started to convert everything? Are we wasting out time. For example many third party payment module use the Mage namespace and put their code in the local directory. (Linkpoint, USAePay)

Answer 1

Technically I don't see any problems keeping 3rd party modules in local/Mage. Keeping your socks in the glove box of your car doesn't cause much problem either neither sense.

Good question by the way.
