Why is the critval table static?

There is a table of critical values at https://github.com/bfast2/strucchange/blob/master/R/critvals-monitoring.R which is used for ME and OLS-MOSUM processes. Why is it static, instead of being generated by a function? The table limits the p-values to 0.001 minimum, which in some cases is not conservative enough. It would be nice if arbitrary numbers could be used instead.
