Spaces in version id in version_manifest

All previous prereleases had no spaces in id field:

{"id": "1.13.2-pre2", 
"type": "snapshot", 
"url": "https://[...]/1.13.2-pre2.json", 
"time": "2019-01-30T15:15:25+00:00", "releaseTime": "2018-10-18T14:46:12+00:00"}, 
{"id": "1.13.2-pre1",
 "type": "snapshot", 
"url": "https://[...]/1.13.2-pre1.json", 
"time": "2019-01-30T15:15:25+00:00", "releaseTime": "2018-10-16T13:40:58+00:00"}

Newest 1.14-pre1 has spaces in id field and naming format is inconsistent with previous prereleases:

"id": "1.14 Pre-Release 1", "type": "snapshot", //...

This inconsistency breaks some of the server control scripts. Is this an error, or behaviour that should be expected in next releases?
