That's just one of the gotchas in instrument flying...if you shoot an
approach into a field where controlled airspace stops at 700' agl you have
to be extra alert just in case. Odds are against anyone doing pattern work
in such conditions, but Murphy's Law always applies.

Why do some airports with an instrument approach (e.g. HIE) lack a surface
Class E to protect the approach? HIE LOC 10 has Class G below 700' AGL,
but
the MDA is well below that height. A plane can legally fly VFR just below
a
700' ceiling along the final approach course, with no way for it to see
and
avoid an approaching IFR plane, or vice versa.
