Short answer: no, Perl is a very rare choice for starting a "serious new application", and Raku's even further off.

In Perl's case, it's not that the production-ready libraries and frameworks aren't there -- they are, and they are fast and stable and in some cases very sophisticated -- but simply that the community of developers likely to start a "serious new application" has passed Perl by for more modern (e.g., Rust, Elixir, Kotlin, Go even if its ideas are old) or ubiquitious (e.g. JS, Python) choices.

In Raku's case, there is not a deep bench of libraries and tools suitable for production.

In both cases, hiring for previous knowledge is not practical.
