And I've been following enough of those debates to know that several of them are debates between theorists over the nature of the derivative theories and their broader implications in cosmology. Always in such cases I get the sense that theorists are getting way ahead of themselves...
We aren't "getting ahead of ourselves" when we've had pretty conclusive proof from observation and experiment that the basics of general relativity work.
But not dark matter, which is what that paragraph was referring to.

From conversations with a friend of mine working in Fermilab, although I should clarify that this is less a problem with the theorists and more a problem with institutions that fund them (universities and government agencies, for example).
Having been involved in reviewing several grant applications for the UK's STFC, I can officially say that "questioning relativity" will not get you in trouble career-wise. Among other things that have been approved are proposals to study Lorentz violation, which at least to me pretty much counts as "questioning relativity".
But are actually related to quantum gravity and m-theory, and -- again, only going by what I hear from gripes -- is a delicate balance of proposing the new theory without offending the biases of establishmentarians.

OTOH, you work in the UK? It could just be cultural.

MY personal bias (call it a pet theory) is that Einstein's interpretation of the implications of Lorentz contractions introduced some potentially unwarranted conclusions and there is actually no need to extend the theory beyond Minkowski spacetime. I think that General Relativity would work a lot better if way could be found to systematically apply Lortentz transformations to a curved spacetime -- say, Minkowsky spacetime with a noticeable curve -- which which point the distinction between special and general relativity disappears.
Well, good luck with that but you've got a fair amount of observational evidence separating special and general relativity to overturn from cosmology, as well as finding a way of making transformations valid only in weak gravity work in a strong gravitational (highly curved, that is) environment.
If I ever did get around to I'd start from the latter -- getting the transformations work in a high curvature -- and then work backwards to the observational evidence to see if the numbers are (or could be made) consistent with it.
