AGC vs. ATC fuses in glider panels

Can anybody shed some light on why manufacturers continue to use glass (AGC) fuses rather than blade type plastic (ATC) fuses in gliders? Is there a certification issue, is it simply inertia? Automotive, marine, heavy equipment, and pretty much everyone else has moved on to the ATC style. From personal experience, a high quality blade style holder is more reliable than the Bussman glass holder which seem to corrode over time. There are some intermediate amp values available in glass that are not in ATC, but this seems like a trifle.
