Documentation mismatch - measurementTagValues and measurementTagKeys

Browsing the functions for exploring a schema, there’s this little warning on schema.measurementTagValues() and schema.measurementTagKeys() :
This function returns results from the last 30 days.
No other functions listed in that page have the same warning.

There’s no mention of this 30-day limitation in either of the two functions’ documentation pages: schema.measurementTagValues (same for schema.measurementTagKeys)

Any thoughts? Can we get confirmation on whether the 30-day limitation truly applies? If so, I’ll submit a PR to include it in each function’s doc entry.
