In our work, we consider that a system is in trouble if more than 50% of its files become orphan (i.e., without a main author).\r\n\r\nMore details on our work in this preprint: https://peerj.com/preprints/1233\r\n\r\nWe calculated the TF for **Leaflet** and obtained a value of **1**.\r\n\r\nThe developer responsible for this TF is:\r\n\r\nVladimir Agafonkin - author of 77% of the files \r\n\r\nTo validate our results, we would like to ask **Leaflet** developers the following three brief questions:\r\n\r\n(a) Do you agree that the listed developer is the main developer of **Leaflet**?\r\n\r\n(b) Do you agree that **Leaflet** will be in trouble if the listed developer leave the project (e.g., if he wins in the lottery, to be less morbid)?\r\n\r\n(c) Does **Leaflet** have some characteristics that would attenuate the loss of the listed developer (e.g., detailed documentation)?\r\n\r\nThanks in advance for your collaboration,\r\n\r\nGuilherme Avelino\r\nPhD Student\r\nApplied Software Engineering Group (ASERG)\r\nUFMG, Brazil\r\nhttp://aserg.labsoft.dcc.ufmg.br/"}}
