Citation pages
The quotation templates are too much in flux to be of much use, as likely as not everything I added in template form would display as a module error by next week. Also, they don't add any value, they are purely for formatting, so they needlessly slow down page generation. If there is a good reason to use them I will switch, but as it stands it is just as easy to run a bot to update formatting if it needs to be changed in the future. As far as marking with a sense, I think there is value, and there is no good way to associate a quote with a sense -- in fact there is no good way to associate anything with a sense, which is a major failing of the current structure.
That's a ridiculous thing to say about templates that have been around for years. Do you see any module errors in the thousands of pages that use them? By using plain-text formatting you're creating technical debt for anyone who wants to use or modify what you're doing in the future. This is especially important since you seem to be adding quotations semi-automatically.
As for associating quotes with senses, what's wrong with putting them directly under the definition lines?
The same thing (technical debt) could be said of all content which is added, not sure why this is any different. There are some GP discussion about the things which have been broken by quote templates in the recent past if you like. Re placing quotes under the definition lines, that is not a practice I approve of; I think that there should be a single good usage example for each sense and all other quotations should be in the Citations namespace.
If I want to use citation pages in the future, am I to be expected to maintain a database of all the separate formatting practices of every editor that has contributed? Or can I just download mwparserfromhell and parse everything with a single set of rules? And yes this does apply to all content, but especially here where there's so much variation between different editors' formatting preferences, and a simple solution to alleviate it. That's what I'm talking about when I say technical debt.
At this point 99% of the Citations namespace adheres to the formatting I am using, so that will get you most of the way there. The simple solution is also a poor solution, which is why I am not using it. The current format adheres to the suggested format at WT:Quotations, and assuming that most people are using that format. If you would like to propose a new layout which involves templates, I am happy to have that discussion and will abide by its outcome. I will also run the bot to update all of my previous additions should a new format be enforced. Using the current quotations templates, however, adds risk and overhead without adding any value that I can see, as I said above.
