Exegetical Payoff in Grammatical Research

Here’s a question for you. It’s one that I’ve been pondering for some time.

Should placing a priority on exegetical payoff in linguistic & grammatical research be viewed as a strength or a weakness?

Thoughts, anyone?

It seems to me that there is a rather hefty group of NT scholars who would hold that linguistic & grammatical research that doesn’t aim for exegetical payoff is not useful.

Of course, to my mind, this stands over and against the basic aims of linguistic research more broadly.

I’m curious, though, whether there are any among my readers who would hold such a view and I would welcome any input or explanation as to why exegetical conclusions should be treated as an (the?) end goal.
