You could also have
<meta name="intent" content="http://webintents.org/share image/*">
or some such. Splitting a string on spaces and using the result is not
that hard and a common pattern. And seems like a much better alternative
than changing the HTML parser. Especially changing the way <head> is
parsed is hairy. Every new element we introduce there will cause a <body>
to be implied before it in down-level clients. That's very problematic.
