Its never been a problem for me. Normally for time series data you handle this by creating a new index every day. For non-time series data I basically do this: http://www.elasticsearch.org/blog/changing-mapping-with-zero-downtime/
It has the advantage of letting me change the mapping and analysis configuration in the process. I can imagine situations where not having shard splitting would be painful but I haven't been in any.
