As suggested above, whoever wants to see progress on this should start developing a plugin that hooks into gcc/c-family/c-format.c. Whether your plugin will parse an attribute, a pragma, an internal representation or define the formats programmatically is up to you. The important thing is to figure out what plugin hooks you need in GCC to make it work, which will require making the format checking extensible at runtime. Until you get that part working, there is little benefit in discussing any possible syntax.
