  The purpose of the comment is to point out that the leading term of the
Ginzburg-Landau nonanalytical correction to the interface tension of
Bose-Einstein condensates with strong segregation and the surface tension of
extreme type-I superconductors are described by a common coefficient derived
from the universal equation for the phase boundary. The agreement between the
numerical value of the coefficients gives a hint that this can be an exact
result which deserves to be checked. The outcome will be of interest for
physicists working in both fields.
