'Usability' is based on human demands. But science is about nature and
based on observations that are not necessarily connected to human
experience, let alone human demands.
But quite often scientific knowledge could be used in unexpected
circumstance. Therefore science is possible in realms like remote
galaxies or in times shortly after the big bang, what serves not
practical purpose.
Scientists are also unable to deal with special interest groups, since
science can only be done in the way, that only positively true results
are the goal of research.
This could eventually harm certain interest. But science cannot
intentionally produce results, which are a little off the right track.
Technology is more related to the production of things. And produced
things should be useful and should function well. But technology is not
the same thing as science.

Personally I think, that SRT is not correct.
The reason is, that SRT hinges on velocity, while I assume effects by
acceleration.
E.g. the so called 'twin paradox' cold be 'de-paradoxed' by focusing on
acceleration.
(This would also explain the 'Pioneer anomaly'.)
So in this case I would take (almost) your position.
