Allow simple_tag to parse @/:/- attributes

[Giannis Terzopoulos]

I'm following up on the forum discussion: ​https://forum.djangoproject.com/t/proposal-allow-simple-tag-to-parse-attributes/36769

I think a sensible first step is trying an opt-in argument as Adam suggested, e.g., allow_all_attrs=True or perhaps allow_all_html_attrs=True.

For implementation details, I propose:

1. Whitelisting common punctuation characters (@, :, -) for attribute names
2. Making these attributes accessible directly (only) from kwargs, such as kwargs["@hello"]

Hello Giannis, thanks a lot for opening this ticket and sharing the idea in the forum!

I took a look at the related forum thread, and while I think you are following the right procedure, I feel there is not enough consensus around this yet. As far as I can tell, only Adam has expressed support, and the use case and overall value of the feature still feel a bit unclear (at least to me).

I'm going to close this ticket as wontfix for now, but I'm definitely happy to revisit and reopen it if the idea gains more traction or if there's a clearer picture of the need and benefit. I'll also cross-post in the forum to invite more discussion and see if we can get a broader sense of interest.

Thanks again for taking the time to bring this up!
