Support of "annotate_template_file_names" or equivalent

[ghost]

Recently in Rails 6.1 was introduced option to annotate rendering of templates with some debug comments. Internally such behavior is handled by actionview/lib/action_view/template/handlers/erb/erubi.rb:

if ActionView::Base.annotate_template_file_names
  properties[:preamble]   = "@output_buffer.safe_append='<!-- BEGIN #{properties[:short_identifier]} -->\n';"
  properties[:postamble]  = "@output_buffer.safe_append='<!-- END #{properties[:short_identifier]} -->\n';@output_buffer.to_s"
else
  properties[:preamble]   = ""
  properties[:postamble]  = "@output_buffer.to_s"
end

https://github.com/rails/rails/pull/38848 That's very useful developer-time-saving feature, especially on projects with complex layouts.

Is there any way to enable behavior like this in hamlit? (register callback, additional prefix handler, etc)
