Some of the mentioned issues are possible with the integrated lensfun
library.

Title:
  suboptimal usage of EXIF data

Status in Hugin - Panorama Tools GUI:
  Fix Committed

Bug description:
  it seems to me that hugin assumes by default a rectilinear lens and
  calculates HFOV based on the focal distance reported by EXIF and that
  default assumption.

  Is it possible to take the EXIF-FOV instead, and to infer the lens
  type by comparing the expected focal distance with the EXIF-
  focal_distance?

  Also, if hugin is not able to determine the lens type, I'd prefer for
  it to leave it empty rather than default to rectilinear. Or to give
  the user a preference to set the default lens type if it can't be
  inferred.
