Rational is to avoid something like

 try {
                final ClassPathModelLoader loader = new ClassPathModelLoader();
                final Set<ClassPathModelEntry> models = new ClassgraphModelFinder().findModels(false);

                for (ClassPathModelEntry entry : models) {
                    final ClassPathModel model = loader.load(entry);
                    if (model.getModelName().contains(element.getLang())) {
                        final TokenizerME tokenizer = new TokenizerME(new TokenizerModel(new ByteArrayInputStream(model.model())));
                        tokenizers.put(element.getLang(), tokenizer);
                        return tokenizer;
                    }
                }
            } catch (IOException e) {
                throw new PipelineExecutionException(e);
            }

and just directly use model.getModelLanguage() (from a user perspective because the model's name might not actually contain the actual language the model was trained for).
