I was excited to see the new feature for restrictive budgeting, but then I was unhappy to see it only offered in enterprise plans. It seems to me that the main difference between pro and enterprise has to do with team features--timesheets, expense reports, member management etc. whereas restrictive budgeting would be a great benefit to many pro customers who do not need the team features..
I would encourage you to offer this new feature to pro users as well.
The way we see it :
as your business grow you may need more and more automation, control, restriction and validation. This is what guide us when comes the time to choose which edition gets which feature.
In that case, restrictive budget gives more control over budget spending, thats why it is offered in the Enterprise version.
