"Weights" and "download" options in config file

[V. K.]

The base_config.yml includes these options, under model: base_network:

# From which file to load the weights.
weights:
# Should we download weights if not available.
download: True

As far as I can tell, these are not used in the code. What is the intended use of these settings? Is there any way to specify the location of the base network checkpoint, besides changing the LUMI_HOME environment variable to set a different default path?
