OK, I am sorry. Good arguments. I was removing explicitly discouraged tag building=building and in this case I understood from the source only that it is a skyscraper. In the table i see "Office". Is building=office a good tag? Actually https://www.skyscrapercenter.com/building/6-8-parramatta-square/31473 suggests building=office height=223.3 building:levels=53 website=https://www.psq.com.au/, but you removed it, so maybe you have other ideas. Apparently you are mapping in Sydney, probably you have much better chances to check the facts yourself than I, so you can add the tags I suggested together with source=https://www.skyscrapercenter.com/building/6-8-parramatta-square/31473 or not, I probably should not do anything against preferences of local mappers.
