It is your comment that is less useful. You will get no sympathy for your opinions if your opinions include pointlessly limiting what people can do.
Inconsistently, you limited Nicolosi Globular, Fournier I and GS50 (and some that I missed).
It is your thinking and knowledge that are inconsistent. I did not limit Nicolosi globular or Fournier I; what is in Geocart are how those projections are defined by their inventors. If you do not like that, then feel free to conduct a séance and snottily berate their inventors for not fulfilling your obsessions centuries in advance.

I limit GS50 because GS50 deteriorates into a non-projection not far outside of the boundaries I gave it. (It does not fulfill conditions of bijectivity.) Geocart requires a projection to be bijective for several reasons.

But where did the creator of extruded globe originally state that the projection may be extended beyond a hemisphere, and the spacing of parallels must be mirrored around the equator? It's not like removing the restriction (as unnecessary, if not more, as the non–existent restriction of the projection being limited to a hemisphere) of

I am the creator; I can do with it as I like.

This is your unfair advantage, that you can be selfish and rude. Just like strict parents, or teachers.

Nobody prevents you from inventing your own projections or writing your own software. As for selfish and rude, well… go find a mirror. People don’t exist to arrange everything the way you want it.

The quote about “mirroring” is not mine; it is yours. Do not attribute what you write to me.

It’s not about bijectivity. It’s about having 17 extra parameters for no reason that anyone on earth but you care about.

To my brain, that's the truth. I didn't know that if some "liquids" leak out of my brain, then you are insta–mad... just like my mom, which I hate.

English sometimes may contain long distances between related word combinations. My sentence, "zoomed out", is "It's not that ... will sacrifice bijectivity either.". So that's just redundantly agreeing with me...

You said that the reason Nicolosi Globular and Fournier I are hemisphere–restricted is that they were originally like this. The only situation in which your decision with extruded globe would be consistent, is if some source stated that extruded globe may extend beyond a hemisphere, but the parallel spacing must be mirrored around the equator.

Some source did state it: I am that source.

Your need for my inventions to fit your notions of “consistency” is unfortunate. I fear you will never be happy.

So you are the creator of extruded globe?
