I concur with David. I am actually a heavy user of signing subkeys
because they allow to keep the primary key offline.
I also added an implementation nit:
The 0x19 back signatures were not required for signing subkeys
until relatively
recently. Consquently, there may be keys in the wild that do not
have these back
signatures. Implementing software may handle these keys as it
sees fit.
