Which discussion? 93431e0607e5 ? IMAO the patches don't depend on each 
other.

IMAO:

* The script should not be neccessary once all of my changes[1] arrive 
in torvalds/master. Instead reviewers should say like C'mon dude, what's 
this new plain-HTTP link doing in your patch? We have 2020! Look at e.g. 
93431e0607e5 .

* The program language agnostic algo description of mine should be 
enough. If it's not enough, I shall improve the description.

* Today I've added "If not .svg:". Imagine Torvalds merges the script, 
closes the merge window *and then* someone runs it on a random subsystem 
and discovers a missing condition. Do they have to patch the script, 
wait for the patch to arrive in torvalds/master *and then* patch the 
(other) subsystem, so they can refer to the now patched script? W/o a 
such central "rule on how to HTTPSify links" they'd just describe 
*their* algo. Or (even better) there wouldn't be much more insecure 
links, so the algo could be omitted.

After all please show me one of the big bosses (Torvalds, K-H, ...) 
who'd tolerate to have a...

* written w/o focus on maintainability
* not documented at all
* *Golang* file

... in the kernel tree.

If I correctly understand, you kernel devs write code so that if even 
the maintainer leaves the project, another one could just take over.

How many kernel devs would read and understand (all of them I guess) 
*and maintain that Go script* of mine?
