"Considered harmful" got my attention. What, if any, known harm is caused?

We have many errors of this type but in our case most are due to batch
processes that have a vacuum embedded at appropriate points in the
string of commands in order to avoid excessive bloat and to ensure the
tables are analyzed for the following steps. Occasionally the autovacuum
triggers before the manual but gets canceled.

Any harm?
