Changing Sub-genres: Big Big Train

Less about kicking them out of Crossover and more about them fitting better in Symphonic, but I understand :).

I wasn't too sure where to put this, so I'll leave it here. I noticed recently that Harmonium was re-categorized from Symphonic Prog to Prog Folk; I know this is not something that usually happens on Prog Archives, but seeing it happen just this once made me want to ask: can we re-categorize Big Big Train from Crossover Prog to Symphonic Prog? I'm not really sure what the reasoning was behind putting them under Crossover in the first place, and every single one of their albums at least since 2009 (which is 7 albums, over half of their studio discography) is very definitively symphonic prog. They have lots of 12+ minute symphonic prog epics, including Victorian Brickwork, East Coast Racer, Brooklands, Brave Captain, A Mead Hall in Winter, Roman Stone, Ariel, and Voyager, along with the much lengthier The Underfall Yard and London Song; but even on shorter tracks such as Master James of St George, The First Rebreather, Judas Unrepentant, Summoned By Bells, The Permanent Way, Wassail, On the Racing Line, and The Florentine, they use lots of lush keyboards, complex time signatures, long instrumental sections, elements of various genres such as jazz, classical, and folk, as well as explorative lyricism, all of which are listed on the symphonic prog page as defining elements of symphonic prog. I know there isn't really a standard process for recategorizing as it doesn't happen very often, but I think this is a change that would be very valuable, as Big Big Train is in my opinion one of the best, if not the best, modern symphonic prog band, and I think it would be useful for new listeners to have them sorted as such.
