[en] It is shown that some regular solutions in 5D Kaluza-Klein gravity may have interesting properties if one of the parameters is in the Planck region. In this case the Kretschman metric invariant runs up to a maximal reachable value in nature, i.e. practically the metric becomes singular. This observation allows us to suppose that in this situation the problems with such soft singularity will be much easier resolved in the future quantum gravity than by the situation with the ordinary hard singularity (Reissner-Nordstroem singularity, for example). It is supposed that an analogous consideration can be applied to avoid the hard singularities connected with the gauge charges. (author)
