Whilst it's easy to flame about tabs vs spaces and other bike-sheddy issues online, I wonder how much people really care about it? After all, many people just get on with life when it comes to non-optional syntax, e.g. whilst many people flame about Python's use of significant whitespace, I doubt that's been a major reason for many people to actually use a different language, or some semicolon-and-braces-to-indentation preprocessor.
Perhaps stick to just one, as seems to be the case right now (whichever it is), and mention in the documentation that those wanting the other option are free to e.g. write a patch/fork on GitHub/postprocessor/etc., with the understanding that such support will eventually get merged in iff it's actively maintained for some amount of time, its author/maintainer is active in general development and maintenance for the project, and there's significant community adoption of such a patch.
Whilst not perfect, this sort of approach might better determine who actually cares enough about this to offset the community-splitting effects of allowing both; compared to a general accumulation of online grumbling.
