to trade compile speed & flash size Initially enable the faster mode on rp2040 and espressif, where there's usually plenty of flash available (these advanced techniques save hundreds to thousands of bytes, which is important on a lot of old samd21 boards but is a drop in the lake of a 4MB flash chip)
