often we include content in export templates that is only
relevant in
particular situations.
“export features” allow for the specification of qualities of
the org buffer
being exported that imply certain “features”, and how those
features may be
implemented in a particular export.
now `\usepackage{svg}' is automatically added when exporting a
buffer that
includes SVG images.

As discussed on the Doom Emacs Discord, I strongly suggest
renaming to avoid overloading the term "feature".
To me, your description indicates sinppets are inserted
contextually.
Org has a similar notion of contexts with
`org-capture-templates-contexts'.
A similar name would be better as it does not overload the term
"feature", which already has a different meaning in elisp.
e.g. org-export-backend-contexts
