700mb is with debugging information (this is not the same as -DDEBUG build). We can strip debugging information while retaining a symbol tables. For fennec this made packaged xul go from 16.3MB to 18.8MB (+2.5MB) an unpackaged xul (on the phone) go from 29MB to 44MB (+15MB)[1]. It's not a trivial increase but it's not 700 Mb.
Otherwise we just have to upload the symbols to the symbol server and add code to query the symbols when profiling. We also need to implement an versioning system for XUL. That would have no impact to what we ship but we'd need to modify the build script and have the symbol servers ready to handle this data.
