True enough. I have worked at a company that designed and built other consumer electronics, though, and spent time with people speccing PCBs and custom silicon. > b/c they agonize over parts like this.

Thank you for the perspective. I do understand that changing one component can affect others. Purism isn't a typical laptop company. The addition of hardware switches, to control webcam, mic and Wi-Fi, is one of the USPs for their Librem models. These undoubtedly had knock-on effects for the BOM. Purism was undeterred by that. In that context... I'm just asking for one more switch. So, Youness and others at Purism: if you are reading this, please do spec a momentary switch to control flashing on future Librems. Your security-conscious users will thank you for it. -- coreboot mailing list: [email protected] https://mail.coreboot.org/mailman/listinfo/coreboot
