This comment should not be removed, as the proposed changes only partially resolve what is described.

It is also not clear whether we want to use utils/push here. The reason why this was not done originally was due to performance concerns. As such, I am not convinced that this PR should move forward.

i mean the performance concern make sense it is low i mean should we go with caching the buffer type at initialization and using a fast path for arrays?
what u think on it ?

Needs Discussion
Restore the FIXME comment as requested by reviewer. The comment notes that while @stdlib/utils/push is now used to support TypedArrays, the set accessor for _rowBuffer still needs to be implemented.
Merge the FIXME comment and its clarification into a single line to resolve the 'Missing empty line before comment' linting error.
