Hi, Gentle ping on this series.
v2 tries to address the previous concerns by avoiding per-file software tfm growth, preparing the software transform lazily, and explicitly disabling unsupported key combinations. The main remaining limitation is hardware-wrapped keys. If this makes the feature unlikely to be accepted, please let me know. Otherwise, I would appreciate any review comments on the current direction. If maintainers have any feasible direction in mind, I would also appreciate hearing it. Thanks, Liao Yuanhong
