I think the point was that for some applications (like printers), it is unreasonable to assume that everyone (or even anything close to a majority) will want them globally accessible out of the box. At the same time the majority do want them to work locally out of the box. Without explicit configuration, how would the application distinguish global vs. local accessibility if it only had a global prefix to work with? The alternative is that before you can connect the shiny new printer you bought, you have to wait for the network administrator to install the appropriate filter at the border, or you have to wait for the DHCP administrator to add you printer so that it will be allocated an address that is in the range of an existing filter. There is nothing requiring that you run the network with SL. Just that if you choose to do so, there will be some devices and applications that will require less work. Personally if I were building an auto-configuring device that is most often intended for local-use, I would have it configure only the SL if one existed in the RA, but if there was no SL, configure all global prefixes. This would allow you to run without SL, but allow those that run with it to not worry about those devices being reached without explicit effort to change the default.
