Technically yes (as is always the case, there is always someone who doesn't upgrade) but there is no evidence of any uptake of the pre-V7 chain (no exchanges listing it, no projects claiming to take on support of it, etc.)
One advantage of Aeon over Monero is it can fork but does not have the risk of splitting into 2 or more supported chains because the community is small and can be herded in 1 way towards the real chain.
What is your assessment on Aeon as the first to test Bulletproofs and be the first Cryptonote based coin to release it with RingCT enabled? I reckon the developers should keep pushing it while hardforking is easily managed and while everyone is not looking hehehe.
