I usually use the proper jack for the intended purpose. They are not that expensive. It stops issues with people plugging the network connection in to the wrong jack. When you have service contract accounts, this will save you a service call, and money.
Bingo.
As I said, those here might not share the same issues that I've had such as loose connections where improper jacks/outlets being used, and I've got a nice box of a few thousand keystones with bent contacts that had been installed by the EC's.
Will it work, sure, but is it the right way to do a proper install out of the gate?
Proper tools for the job, the example was an exaggeration, however I've witnessed EC's using linesman's to make up RJ's and BNC's and overcrimping Scotchloks to the point of cutting through the conductors and failing to understand why it won't work properly.
