When backwards compatiblity is a reason for not changing this adding a 
hook can be solution, e.g.

-\def\page_one_place_float_auto       {\page_one_place_float_otherwise}
+\def\page_one_place_float_auto       
{\page_one_place_float_otherwise\rootfloatparameter\c!next}

which can be used with \setupfloat[next=\indentation]
