Apparently something went wrong in the latest updates to g.extension:

{{{
GRASS 7.8.dev (nc_spm_08):~ > g.extension -a | sort
List of installed extensions (modules):
i.pysptools.unmix
i.pysptools.unmix
i.pysptools.unmix
i.pysptools.unmix
i.pysptools.unmix
i.pysptools.unmix

i.pysptools.unmix

i.sentinel
i.sentinel.download
i.sentinel.download
i.sentinel.download
i.sentinel.import
i.sentinel.import
i.sentinel.import
i.sentinel.mask
i.sentinel.mask
i.sentinel.mask
i.sentinel.preproc
i.sentinel.preproc
i.sentinel.preproc
...
}}}

Somehow, there is a undesired loop.

Since the list of local extensions is scanned at startup time, it is now
REALLY slow when you have a number of extensions installed.

Do not write metadata if the addons already exists in the metadata file:
