  Different versions of consistent canonical realizations of hypersurface
deformations of spherically symmetric space-times have been derived in models
of loop quantum gravity, modifying the classical dynamics and sometimes also
the structure of space-time. Based on a canonical version of effective field
theory, this paper provides a unified treatment, showing that modified
space-time structures are generic in this setting. The special case of
Euclidean gravity demonstrates agreement also with existing operator
calculations.
