First off lets be clear this is a proposed merger not a deletion Looking at your argument of other stuff exists the only HD specific example that you have mentioned List of DirecTV local channels with HD compares the availability of affiliated HD channels between cities not a million miles away from this page comparing channel availability between platforms The other examples that you have given are lists per platform as you said The fact is HD channels on Sky do form a part of Sky Digital and not another platform called Sky HD HD channels are clearly labelled on List of channels on Sky Digital as being in HD were applicable There is absolutely no distinction in the amount of HD content shown if it simulcasts with an SD channel etc on the same channel between platforms There is no need for a list of channels in a certain broadcast format on a certain platform and it seems like content forking and listcruft You also mentioned size labelling this page as potentially unwieldy there are clear guidelines for the size of articles and compared to the other lists that you mentioned this page could double in size without problems If you want to talk long term then in the future its likely that being in HD or knowing if a channel uses upscaling wont be especially notable just as being in  or using widescreen switching or stretchingzooming isnt today and at some point this page could also end up being merged or otherwise By the way there is a List of television stations in the United Kingdom foreign versions may be found at Lists of television channels and I agree that it is somewhat impractical for certain tasks As for Andrewcrawfords actions HelpMerging explains that If you think merging something improves the encyclopaedia you can be bold and perform the merger as described below Because of this it makes little sense to object to a merger purely on procedural grounds eg you cannot do that without discussion is not a good argument If the merger is controversial however you may find your merger reverted and as with all other edits edit wars should be avoided If you are uncertain of the mergers appropriateness or believe it might be controversial or your merger ends up reverted you can propose it on either or both of the affected pages A proposal had been made in August  If there is clear agreement with the proposal by consensus or if there is silence proceed with the merger There was silence so he did nothing wrong With regards to DarkLight he did not post any kind of edit summary with his edit since Andrew does not a appear to be a regular contributor to List of HD channels on Sky HD he could have perceived that as vandalism and vice versa
