What are the disadvantages of FRAX?

Could you elaborate on the potential drawbacks of FRAX? I'm interested in understanding its limitations and any challenges it might face. For instance, how stable is its pegging mechanism? Are there any concerns about its governance structure or the trustworthiness of its collateral? Also, how does it compare to other stablecoins in terms of scalability, transaction speed, and fees? Lastly, are there any regulatory concerns surrounding the use of FRAX that investors should be aware of?
