# the persistent nodemap feature needs to stay experimental as long as the Rust #
# extensions are an experimental feature. # The case was discussed that the 5.6 sprint and the following was decided for
# feature that have an optional fast implementation (and are a performance
# regression in the others)
#
# * If the fast implementation is not available, Mercurial will refuse to
# access repository that requires it. Pointing to proper documentation
#
# * An option exist to lift that limitation and allow repository access.
#
# Such access will emit a warning unless configured not to.
#
# * When sufficiently mature, the feature can be enabled by default only for
# installation that supports it.
