Think you're being a little harsh tbh.
The Sandberg configurator is one of the, if not the, best configuration sites online. It gives you literally thousands or options using the stock electronics, if you're serious about buying a bass, a quick email to a distributor will let you know the additional cost.
Don't forget, software development is very expensive, even adding a seemingly simple option can work out to be days, if not weeks of work, depending on how many parts of the site the change touches.
