Yes, more than 1000 clones might seem like a lot for the Array modifier, but I have encountered situations where I need more than 1000 clones.
This hard coded limit of 1000 clones feels unnecessary and should be removed, or at least significantly increased.
Edit:
It seems like this clone limit applies to the modes Total Dimension and Relative Offset, which means using Fill mode as suggested by a user can provide a workaround since it allows for generating more than 1000 clones. However, in these modes the number of clones are determined by other factors than clone count, so setting a specific amount of clones can be tricky and tedious. It would be better if the other two modes had the clone limit extended or removed completely.
