Yes, but... Where do you depressurize *to*?

Either you have to have vacuum lines running all through your ship, with some sort of valve on them, or you go with reliable heat-proof air pumps and some sort of large fire-proof plenum. The latter takes up an awful lot of volume, and the former seems prone to leaks and malfunction. And, of course, this probably doesn't work well in Jump.

When I designed my HighPoints / Chandeliers I went with a pressurized delivery system full of pure nitrogen and an oxygen binder (cf Halon). Yes, this can malfunction, but this would (usually) affect only one room. HighPoint rooms also come with oxygen sensors, sirens, and emergency isolation suits aka rescue balls. YMMV.
