I'm well aware that WordPress by default does not process shortcodes in the sidebar. My question is why.
I'm building a very small plugin that exports some content when the shortcode is present. This will be primarily used in the content area. I want to allow the user to display that content in the sidebar and I'm debating including the one line fix to enable the shortcodes rather than adding ~50 lines of code to create a widget.
Is there something going on under the hood that is a good reason to avoid the shortcode in the sidebar? Is it simply a convention?
