That is correct, or almost. The currently accepted interpretation is
that of Minkowski.

Relative to which observer? I meant relative to Lorentz'ether, inertia
may actually decrease (although we can't know of course).

I am happy to hear that some of my contributions are not in vain.

The mathematical consistency of SRT has been extensively tested. In
that sense we can be quite sure that it isn't self contradictory. But
in the way you formulated it yourself above, a proposed interpretation
can be self-contradictory because interpretation can be independent of
mathematics.

Here is an attempt:

In the Lorentz-Poincare interpretation of SRT, the relativistic
effects are caused by movement relative to a stationary ether, and
these same effects can be shown to hide such movement from
observation.
