As Dan points out, 250.52(A)(3) specifies several installation requirements in order for a concrete encased electode to qualify as a permitted Grounding Electrode. A pole mount foundation would certainly qualify if it met those requirements.
Even if the requirements are not met, IMHO, any opportunity to inexpensively increase the grounding integrity of a system should not be overlooked, particularly in lightning country. Of course, a code compliant Grounding Electrode System is still required. Bonding a non compliant, but never the less, very substantial additional "electrode" to that system would not hurt anything and quite possibly help considerably.
