Never a good idea.
If a package assumes it as a good practice the best approach would be not to use it.
can you write a query to select all queries started during off-hours last night?
And what about a query selecting all events with writes > certain amount?
With split columns both queries would require table scans, which means reading the whole table into memory and apply filtering in there.
Which is exactly the problem with the current state of affairs in OP's database.
