Good morning. 

With this revert you removed various tags including population, official_name, is_in:*, admin_type:PH and more, which all seem to be well-established and aligned with local mapping conventions.

Please consider reaching out to mappers through changeset comments or direct messages if you have concerns with some of their edits. For general discussions about local mapping conventions there's quite an active OSM PH community channel on telegram (https://t.me/OSMPH).

Given the very generic changeset comment one can only guess what caused you to do this revert. Would you mind explaining the reason for the deletions?

Do you maybe have concerns with the change from designation to admin_type:PH? If so, this topic was discussed and voted on in the above-mentioned community channel and wiki documentation has been updated accordingly. 

Generally reverts should only be done if you are very confident that entirety of a changeset is problematic. Most of the time it's better to just load all affected data of a changeset into editor and then selectively modify tags/geometries. This is to avoid reversion of accompanying changes (e.g. updating of population).

Best regards.
