Will I break Solr if i change this to default to not multi-valued?
If you are only indexing one value in those fields, then setting multiValued to false will not break anything.
If an indexing request ever comes in that has more than one value for a field that does not have multiValued set to true, that document (and any others following it in the batch) will fail to index. It is likely that the reason the default is set to true is to avoid complaints from users who DO send more than one value.
In situations where copyField is used to copy more than one field to a target, the target must be multiValued, or that indexing will also fail.
