Query: Remarks on the Bojowald--Paily paper Deformed general relativity   A couple of technicalities in the paper M. Bojowald, G. Paily, Phys. Rev. D
87, 044044 (2013) are discussed. The explicit formula given there for the
function entering the modified hypersurface-deformed algebra, which presumably
originates in loop quantum gravity, seems to be oversimplified, and the
embedding of deformed special relativity in deformed general relativity
proposed there for spherically symmetric models raises some questions as well.
