Yes, it is.
Again: Sticking an unfinished, janky feature into a piece of software communicates to the user that your software is unfinished and janky. Good software developers usually see that as a bad thing.If You don't like railway-tunnels for ships (me too), then just don't use them - convert them to the ship-depot-like-water-tunnels with 2-tiles-long tunnel entries.
If you want a feature in mainline OpenTTD, it has to actually be finished.
And that is why my first statement in this thread is still true: because your unfinished prototype for a heavily-limited approach to stations in tunnels and on bridges is not the same as an actual completed feature which is ready for inclusion.
That question is entirely misleading.Which restriction is more strong: A) to have a possibility to use a tunnel as a platform (or its part) with need to use "Go non-stop to..."-orders and waypoints or B) to don't have any such possibility?
Let me put it that way: If you downloaded a painting software that does not support any shades of green, would you say "well, this is better than not having any colors at all" or would you say "wow, this software is a giant piece of s***"? I would most certainly go for the latter option.
Again: Having a feature which comes with restrictions that are completely nonsensical to anybody who doesn't have a deep understanding of how the software works internally simply communicates that your software is unfinished, janky and bad. OpenTTD does not want to be percieved as unfinished, janky and bad. Most software projects don't.
Nobody is doubting that your patch does what you say it does.Could you tell your opinion: does it provide its declared possibilities?
It is simply not fit for inclusion in OpenTTD mainline. You said: "It seems, that OpenTTD Developers have no interest (or have other reasons) why they don't want to (or can not) do anything with this patch". And I simply explained to you my theory on why the OpenTTD developers are not interested in your patch. My reward is having you go at my throat and call me a liar. That'll teach me.
And I am not trying to dissuade you from continuing to promote your patch pack. I play with a patch pack myself. You are free to make it and promote it for as long as you want.
