Increase the number of future enterable periods in our ledger setup.

Hi

We are considering a change in the number of future enterable periods in our ledger setup.
It is 12 today.
We would like to change it to 60.

I found this note on the subject:
https://support.oracle.com/support/?kmContentId=2533101&page=sptemplate&sptemplate=km-article

The note says that it is not advisable.

I think that the note says that it is not advisable to decrease the number of periods.
Do you think it would be okay to increase the number of periods?
If the anser is No, what is the reason?

Best regards
