Who is the "we" in "we use the convention"? All Wikipedia language communities?

I have seen this convention in place in the English, German and French Wikipedias. I have not checked any others.

I spoke too soon: the French Wikipedia also often uses

<center><math>x^2=-2</math></center

which is closer to the TeX-way of doing things. It's also hard to do in VE.

^^ that's something supported by ve. You can select displaystyle in the ve menu.

You can set <math display="block"> in the formula tool (the "options" tab). That appears to add valid, non-list-formatting indentation on the English Wikipedia and centering on mediawiki.org. Presumably there is a difference in the CSS definitions between the two wikis. One significant advantage to this is that if you copy formulas between Wikipedias, it will always be correctly displayed in the local style.

Related to this, on WikiToLearn we've been adding the <dmath> tag as an alias for "displaystyle" math also supporting TeX environments (align, matrix, ...).

Is it something that upstream would like to take a look at? It has proven very useful for all of our editors of Physics/Maths books!
I am eager to collaborate and merge our efforts as much as we can :-)

@Jdforrester-WMF can I quote you for writing formulae that way? Too many people claim formulas would be better, which I do not like at all.
