 You could regard as 'SRT' also the modern version(-s) of Einstein's origional theory.
 This would be the relations in 'flat' space, where objects fly in streigth lateral motion and non-accelerated objects.

The one and only Special Theory of Relativity is only
valid in "flat spacetime" where there is no gravitation.
In flat spacetime non accelerated objects will move along
straight lines in an inertial frame of reference.
But accelerated objects can move in along any curve depending
on the accelerating force. Obviously!
Examples of accelerated motion in flat spacetime:

I would regard this interpretation of 'SRT' as perfectly possible, too.

There is no interpretation of SR where objects can't accelerate.

 This is the 'special' case of GR, which covers accelerated FoRs.

GR simplifies to SR when there is no gravitation.
Both SR and GR "covers accelerated frames of reference".
But SR only in flat spacetime.
