The new feature is promising as an alternative for U+200B zero width 
space as an escape character (info "(org) Escape Character"). It may 
adjusted to allow really plain text markup instead of a character 
invisible by default:

(org-export-string-as "Example of &_{*intra*}&_{/word/} markup"
                      'html
                      '(:export-options (body-only)))
"<p>
Example of <span><b>intra</b></span><span><i>word</i></span> markup</p>
"

However to produce clean export result <span> elements should not be 
added if no attributes are specified. My expectation is

"<p>
Example of <b>intra</b><i>word</i> markup</p>
"
