What is the exact source of these edits? Also, please use meaningful changeset comments (other mappers should know what are your edits all about)

I would certainly disagree with this being trunk. The established convention is that trunk (in Canada) would be a non-freeway that is part of the National Highway System, and for the Winnipeg area, they would be Provincial Trunk Highways 1, 75, 100, and 101.

wrong comment, should be: [Pilar, Sorsogon] revert edit on segment of Maharlika Highway

Wrong comment: should be [Pola and Pinamalayan, Oriental Mindoro] undid edit on section of Calapan South Road.

I'm wondering how this edit cover a such large area of the world.

Reverted. Reason: previous road classification not reflective of traffic patterns and importance, plus edit warring and unwillingness to communicate.

Again, please stop all of your unwillingness to talk about why these should be classified as tertiary. I'll revert this, along with you other latest edits. This is turning into an edit war, and you may be blocked for not trying to communicate with other mappers.

The previous classifications do have an effect on routing, so please stop reverting changes that should better help. Sorry that I might call you stubborn about this, but please don't touch road classifications without providing good reasons why the previous classification is right.

Sorry, this is what I meant to write here:
"Again, you are trying to revert the ongoing road reclassification work, which is being done to improve routing. If you can, please stop touching road classifications without discussing it with other mappers, or providing any reasonable explanation."

And again, please do not change road classifications without providing any good reason or discussing it with other mappers.

Clarification: comment should be rather like this: [Lipa, Batangas] reverted edit that removed roundabout and expansions of SM City Lipa (apparently armchair mapping using outdated Bing imagery)

Reverted, as the changes are based on outdated imagery.

I really don't see anything that makes the roads you mentioned trunk road (and keep it so). As long as I can say, roads like EDSA, C-5, Roxas Boulevard and Road 10 better qualify as trunk as the main routes between SLEX and NLEX until Skyway Stage 3 opens. If possible, please ask the community first before you change any road classifications you don't think to be correct.

I don't see GPS signal issues as a reason to tag them as covered (see covered=yes page on OSM Wiki).

I don't think marking the at-grade sections with Skyway above it should be marked as tunnel, as the layer tag already implies it.

Reverted. Not a major street really.
