We already have the rdvl helper programs which can be used to read the actual vector length from a shell command. I'm not sure there's a particular use case for adding something to to this program, and I'm not sure the complexity is worth it especially given that we've got both the actual and to be inherited vector lengths to be considered in the UI. This program exists to allow you to configure vector lengths for the stress tests without having to write UI code in assembler.
