Elimination of LTS?

Did the team eliminate long-term support (LTS)? I noticed it's present in the v14 lifecycle doc but absent in the v15 lifecycle doc. Is that only because v15 is a STS version or will there only be STS versions going forward? The v15 doc seems to state pretty clearly: > Azure PowerShell currently ships only one type of generally available release: Standard Term Support (STS). All major versions are considered STS releases. So, if this is true, does this mean Az PowerShell versions are supported for 6 months at a time with no overlap? i.e., previous version goes out of support as soon as the new STS version is released.
