Regression of #4539

@kernwig we're trying to sync master to 2.3.0 via #5072, #5079

We might need your help to review later due to merge conflicts in the TS generators or templates.

Post-merge, it looks like the regression of #4539 is fixed, but the Date bugs reported under #4969 are back. I will once again modify my working copy, and then will be able to confirm this regression is fixed.

Post-merge, api.ts has added an export const APIS, trying to export services that were not imported. I think this is an obsolete line from the v2.2 branch. Simply removing it allows for successful compilation.

[kernwig]

Confirmed that the #4539 regression is resolved.

Leaving this issue open to track api.ts regression.
