 # Note
 
-This PDEP was originally accepted on May 8, 2023. However, after reviewing feedback posted
-on the feedback issue [#54466](https://github.com/pandas-dev/pandas/issues/54466), we, the members of
-the core team, have not decided with moving forward with this PDEP for pandas 3.0.
-
-The primary reasons for rejecting this PDEP are twofold:
-
-1) Requiring pyarrow as a dependency causes installation problems.
-   - Pyarrow does not fit or has a hard time fitting in space-constrained environments 
-such as AWS Lambda and WASM, due to its large size of around ~40 MB for a compiled wheel
-(which is larger than pandas' own wheel sizes)
-   - Installation of pyarrow is not possible on some platforms. We provide support for some
-less widely used platforms such as Alpine Linux (and there is third party support for pandas in
-pyodide, a WASM distribution of pandas), both of which pyarrow does not provide wheels for.
-
-   While both of these reasons are mentioned in the drawbacks section of this PDEP, at the time of the writing
-of the PDEP, we underestimated the impact this would have on users, and also downstream developers.
-
-2) Many of the benefits presented in this PDEP can be materialized even with payrrow as an optional dependency.
-
-   For example, as detailed in PDEP-14, it is possible to create a new string data type with the same semantics
-   as our current default object string data type, but that allows users to experience faster performance and memory savings
-   compared to the object strings.
-
-While we've decided to not move forward with requiring pyarrow in pandas 3.0, the rejection of this PDEP
-does not mean that we are abandoning pyarrow support and integration in pandas. We, as the core team, still believe
-that adopting support for pyarrow arrays and data types in more of pandas will lead to greater interoperability with the
-ecosystem and better performance for users. Furthermore, a lot of the drawbacks, such as the large installation size of pyarrow
-and the lack of support for certain platforms, can be solved, and potential solutions have been proposed for them, allowing us
-to potentially revisit this decision in the future.
-
-However, at this point in time, it is clear that we are not ready to require pyarrow
-as a dependency in pandas.
-
+This PDEP is superseded by PDEP-15.
