Well, all images are by default linked to their file source, be it in a lightbox, file page, or whatever environement, but it leads to the image itself. This is the default. If the editor has an EXTRA option to change the target, we expect editors to know what they're doing and that they would use this OPTION wisely. If the image gets retargeted by the editor, why should it be retargeted on one device type, and not on another? We call this inconsistency. It's not a matter of considering Gamepedia worse or better.
Imagine if we did this with all wikitext options: wait this one, should not do this, because users on that platform think like this. That other command, hum... Let's make it bahave the opposite way, because users on devices X think that other way. Where is this even documented?!
And even if this cr*p gets documented, the thing I see here on Fandom more and more is that we have to allow people to edit without wikitext because it's "hard" for a lot of people, that visual editor is great (even if it messes with the code every f* time). We're even banning Special:Forum and forcing people to use sh*ty Discussion (WITHOUT wikitext). Not going far on that discussion, just to give a background for my question: how would wikitext be any easier if we get different results out of it, depending on the device it will be rendered? It makes no sense.
