Hi,
it is great that 1.18 supports the normalization of symbolic <DEL> notation. But some of the called deletions in my data are of length bigger than 20.000.000 bp (they are probably false positives, but these things might happen with e.g. with radiotherapy). Instead of the symbolic representation bcftools norm transforms them to explicit representation, so it write the complete 20.000.000 bp to the records ref field.
While technically correct, I would HIGHLY prefer the previous <DEL> instead. Maybe an optional flag or threshold when to do the explicit / symbolic representation would be nice
