Nah. Its very fashionable. juts bang in hydrated line instead of
portland and slap it in.
And hope it doesn't rain for a couple of months. Hydraulic lime might
be a better bet

Just use 1:1:6, or even approach 1:2:9.

1:1:6 is very common, but has been widely criticised by the experts,
since the lime content causes thr cement to not checmically set
properly, and the cement clogs the pores preventing the lime going off
properly as well. The result is regular failures. But its still
commonly used. I expect it'll take another 10 years for the knowledge
to permeate.
