@JenMsft They tried removing it, but as soon as they detached part of the railing, the elevator on the opposite side of the building started moving horizontally instead of vertically.
@hamato@JenMsft I've seen places like that. It's most likely in a performance area (stage behind our point-of-view) and there'd be a table for 2-4 there - it's raised so that the seated people can see over the heads of people standing in front of them. The stairs most likely go up to a balcony area from where people can also watch the performance.
@JenMsft If this is really legacy code you can test: if you remove just one stair and the whole house collapses and nobody knows why, then it was legacy code.
