[QMalcolm]

There's an open question on whether we're trying to get #187 in 0.4.0

[r-richmond]

Can we get #134 added?

[QMalcolm]

@r-richmond apologies that I didn't respond sooner to this. DSI 0.4.0 was kind of a mad dash for us to ensure compatibility between MetricFlow and dbt-core. #134 is something we want to do, but are trying to balance with the other things we need to get done and the bandwidth we have. We'd absolutely welcome contributions to get us moved over.
