Profile Safe Mode

So I tried to check whether that safe-mode feature allows to disable 
bundled and/or shared extensions:  With current master on Linux, 
'soffice --safe-mode' starts LO and displays a "Safe Mode" dialog that 
offers (among other options) an "Uninstall extensions" radio button with 
attached check boxes "Uninstall all user extensions" and "Uninstall all 
extensions (including shared and bundled)".  But, even after selecting 
the "Uninstall extensions" radio button, the two check boxes remain 
disabled.

Can somebody clarify?
