It can lead to very large transaction logs and very long playback of the tx log on startup. If Solr goes down during indexing to something like an OOM, it could take a very long time for it to restart, likely leading to people restarting it because they think it's stuck... and then it has to start at the beginning again... (Ref: https://lucidworks.com/post/understanding-transaction-logs-softcommit-and-commit-in-sorlcloud/) ... Infrequent commits might be better than none (but definitely you do not want not frequent commits, certainly not after every batch, or even worse after every doc).
