@momchil-velikov's commentary applies globally and is not specific to FPMR. 
Which is to say, Arm switched a while back from "all system register need to be 
protected by their feature flag" to "only protect system registers where there 
is a need".  The rational is that we see it as being unnecessarily burdensome 
to asm writers to force them to use a feature flag in order to use the pretty 
printed version of an instruction they can already emit (this is especially 
true when dynamic feature detection is used, rather than wanting to explicitly 
say the feature must be present) .  We've no direct plans to revisit all 
previously implemented system registers unless there's a specific need.
