Review Comment:
guys, I admit I missed some important aspects of this patch
@ayushtkn: I would appreciate it if you can elaborate on the "argued" points
in the PR description: actually, a thorough review needs a solid geospatial
background, which I obviously don't have :) so the PR description should be
clear about these points, especially in the "Does this PR introduce any
user-facing change?" part, as otherwise, when the context of this change fades
away, it's going to be extremely challenging to answer any questions
