That's just the workaround until a fix is available for your CPU, if I understood correctly.

No, that's not what I meant. In the past, Intel's microcode updates have simply disabled the broken functionality as an official solution.

You specifically said the fix might be to permanently disable HT.
The TSX situation was indeed unfortunate, I have one of the affected CPUs. But it was a new feature that was broken, not something that used to work, so the bug's impact was less serious, and disabling the feature didn't have too much of an impact.
