No: the /dev/[sh]d* devices are as stable as they have always been.
ONLY rules using %e (the /dev/cdrom-like aliases) are unreliable.

This is a possible solution, but somebody would need to add to ifupdown
whatever is needed to support this:

# find the interface name using the MAC address
SUBSYSTEM=="net", SYSFS{address}=="?*", \
	IMPORT{program}="/sbin/ifup --mac-to-name $sysfs{address}"

# if it did not work, try using other properties
SUBSYSTEM=="net", ENV{IF_NAME}!="?*", ..., \

# set the interface name, if found
ENV{IF_NAME}=="?*",	NAME="$env{IF_NAME}"
