The USG has been aware of the plight of the Accidental Americans quite a few years now, i believe it came up in the Obama administration but no relief has been provided yet. It is the Fatca that exacerbated the problem because in some places, accidentals are being turned down for financial services, bank accounts, mortgages, loans, career advancement to name a few. Accidentals without a US birth place should ignore everything unless they intend to move to the USA.
Prior to Fatca people went about their business without a clue (as did I). I also never lived in the USA as an adult and had no way of knowing these rules as education is non existent until Fatca.
I don't think citizenship taxation will be abolished so easily. The USA is in debt, and no one wants to be seen to be helping rich homeland Americans avoid tax by moving overseas. If the laws do change, they could also be changed back. The best advise is to evaluate your relationship with US citizenship. Renounce if you see no benefit to US citizenship. There is the option to ignore everything too but one must weight up their own individual circumstances as to the risks.
