My current solution is now:

void convert_vcf(cmd_arguments const & args)
{
    bio::var_io::reader reader{args.input_file_path};
    bio::var_io::writer writer{args.output_file_path};

    for (auto & rec : reader) {

        if (rec.id().starts_with("sim_sv_indel")) {
            for (auto & info : rec.info()) {
                if (info.id != "SVTYPE") continue;
                if(auto* s = std::get_if<std::string_view>(&info.value)) {
                    std::string alt = "<" + std::string{*s} + ">";
                    rec.alt() = {alt};
                }
            }
            writer.push_back(rec);
        } else {
            if (rec.id().rfind("sim_sv_indel", 0) == 0 ) {
                seqan3::debug_stream << rec.info().front().id << "\n";
            }
        }
    }
}

I have double-checked this and variant<..., string_view, ...> is indeed not comparable with string_view. So if you want comparison, you would need to compare with bio::io::var_io::info_element_value_type{"INS"} which is arguably not very nice. The workaround you chose is also very valid, and probably what I would recommend, too!

However, I see another problem with the code:

            for (auto & info : rec.info()) {
                if (info.id != "SVTYPE") continue;
                if(auto* s = std::get_if<std::string_view>(&info.value)) {
                    std::string alt = "<" + std::string{*s} + ">";
                    rec.alt() = {alt};
                }
            }
            writer.push_back(rec);

I think you are using the default records, which means that alt is std::vector<std::string_view>. You are assigning a std::string to this within the inner if-statement. That string goes out-of-scope at the end of the if-statement, so the string_view is "dangling" when you push the record to the writer.

You can fix this by defining alt in the same scope that you call push_back()... but if you do bigger changes to the record, it is always recommended to create a deep record instead.

The current main-branch has easy-to-use preset for this.
