We have many configuration validation points (both as must statements and tailf:validate statements) in our schemas. But they really come in way of scalability testing (when a huge load of configuration is done via scripting, where we do not want to test input sanctity but input volume).
Of course, the best solution would be to profile and optimize validation codes. But instead can we instruct confd to disable validation checks all together? Bonus would be to have the knob on run time.
