However, please keep in mind that we have hundreds of megabytes of existing wikitext, and converting this to anything else would be a major PITA. It may be doable but is probably nothing the developers want to spend much time on.
I consider that a minor issue. Ours is the largest wiki on the planet, and converting every page in the database would take a few hours at most, and I consider that a small price for the potential gains of a clean, usable syntax.
