(already mentioned this on forum #197868, but thought nobody would read it there)
I've recently seen a lot of people suggesting this as a good thing to do, but I personally believe that it isn't. The reason field should be kept purely to reasons rather than contain a whole bunch of other suggestions since its all permanently tied to the alias/implication. Additional requests should be edited into the post after its made imo.
Not only does it stretch out the alias/implication pages by having excessively long reason fields (they should all just be something short and informative, it has a forum link for the in depth discussion) it can get misleading.
For example, I suggest the implication anal_sex -> sex and in the reason field I suggest another implication by writing also [[anal_sex]] -> [[anus]]. The first implication would be accepted, however the second one wouldn't be. Any time anybody looks at the implications page and sees this figurative implication, they'll see also [[anal_sex]] -> [[anus]] right next to it, and even though it had never been approved, it could easily give the idea that both were accepted alongside each other.
Additionally, I believe the ability to suggest multiple implications at once would be a great feature. Every suggestion could be added to the alias page and only create one forum thread.
There's a few mentions of this idea already: forum #82308, forum #57397
tl;dr I believe that using the reason field for making bulk suggestions can be confusing and misleading, and that the post created by the form should be edited afterwards by the suggester instead.
