Please, please can we stop trying to satisfy every edge case or extend
the markup to satisfy every possible scenario.

Org's big strength is in its simplicity. This comes at a price -
limitations in what can be done. If those limitations are unacceptable,
then use a richer markup format like Latex, XML, HTML etc.

The point about back end exporter support is very relevant. The 'richer'
the markup, the harder it is to get a consistent mapping for back end
exporters. things quickly become more complex and difficult to maintain.

In 18 years, I've seen requests for inner word markup less than 4 times.
this is not a feature we should even be considering adding to the markup
syntax. 

Org provides a light weight markup, not a fully flexible rich markup
designed to meet any need. It makes the easy stuff simple.
